Experimental Performance Studies of SCTP in Wireless Access Networks*

چکیده
The Stream Control Transmission Protocol (SCTP) is a new general-purpose transport layer protocol developed by the IETF. Compared with TCP, SCTP has two distinct features: multi-homing and multi-stream. Our work investigates the SCTP performance in various network environments, and its availability for different applications. This paper proposes a SCTP multi-homing scheme as the transport layer solution for wireless multi-access networks, using GPRS for retransmission when WLAN connection is interfered, collided or congested. We also evaluate the transport protocol behaviors for e-commerce applications. Through the experiments based on the Linux kernel implementation, we find the SCTP scheme can provide better throughput and more robustness in wireless access networks.

متن کاملThe Role of Regulatory in Price Control and Spectrum Allocation to Competing Wireless Access Networks
With the rapid growth of wireless access networks, various providers offer their services using different technologies such as Wi-Fi, Wimax, 3G, 4G and so on. These networks compete for the scarce wireless spectrum. The spectrum is considered to be a scarce resource moderated by the spectrum allocation regulatory (“regulatory” for short) which is the governance body aiming to maximize the socia...
